发明名称 Endless elastic resistance exercise device
摘要 An elastic resistance exercise device includes an endless elastic resistance member that returns to its original or near original shape and length after being stretched. The elastic member is loosely encased by an endless, gathered fabric sleeve that permits the elastic member to stretch several times its original length and also limits the amount of stretch of the elastic member. Two handgrips are connected to the fabric encased elastic member, and the handgrips are made of a material which is soft and compressible by a user and which returns to its original shape or near its original shape after it has been compressed.
